Patented Sept. 9, 1930 UNITED STATES LOUIS KESSLER, or CHICAGO, rmorsBURNER non NOXIOUS erases Original application filed October 24, 1927,Serial No. 228,161. Patent N0. 1,735,927. Divided and this applicationfiled. December 21, 1928. Serial No. 327,534.

It is common practice to draw noxious gases from mines and other placesand discharge them into the atmosphere. The object of the presentinvention is to produce a simple and novel burner by means of which suchgases may be consumed so as to avoid the obj ectionable efiects whenthey are discharged.

The present application is a division of my application on Mineventilating system, Serial Number 228,161 filed October 24, 1927, whichhas resulted in Patent Number 1,735,927 issued November 19, 1929.

The various features of novelty whereby my invention is characterizedwill hereinafter he pointed out with particularity in the claims; but,for a full understanding of my invention and of its objects andadvantages, reference may be had to the following detailed descriptiontaken in connection with the accompanying drawing, wherein:

Figure 1 is an elevation of a burner arranged in accordance with myinvention, there being a protecting housing therefor shown in section;and Fig. 2 is a central lon gitudinal section through the burner,on alarger scale than Fig. 1. Referring to the drawing, 1 represents avertical flue extending up through a mine shaft or from some other pointat which noxious gases accumulate or are collected. On the upper end ofthe flue is mounted a small reservoir 2 having in the bottomperforations 3 through which the gases may rise. The top of thereservoir is in the form of a cover & having therein a central chamber 5the capacity of which is much less than that of the reservoir. Anopening 6 leads from the bottom of the chamber into the reservoir, whileat the top of the chamber is an opening 7 leading to atmosphere. A gaspipe 8 is connected to the chamber 5 and is adapted to deliver acombustible gas into the chamber through a port 9 in one of the sidewalls of the latter. The gas delivered into the chanr her through thepipe 8 may be ignited so as to provide a pilot light projectinglaterally into the chamber. Consequently, when the noxious gases risethrough the flue, they first fill the reservoir and then rise throughthe opening 6 into the combustion chamber where they are ignited by. thepilot light. The result is that products of combustion of the noxiousgases, instead of the gases themselves, discharge into the surroundingatmosphere.

In order to prevent backfiring through the A flue, I prefer to place inthe same, just below the reservoir, a plurality of frusto-eonicalscreens 10 whose large ends fit tightly in and fill the flue. ber ofthese screens, arranged one above the other, the smaller ends beingpreferably directed upwardly. The screens do not inter fere with theupward travel of the gases rising through the flue, but they prevent theflame at the top from igniting the gases below the screens and producinga backfire down through the flue.

It will thus be seen that I have produced a simple and novel burnerdevice comprising a'large lower chamber and a smaller upper or'combustion chamber communicating with the former; the gases to bedissipated collecting in the lower chamber and rising up into thecombustion chamber where they meet a pilot There may be any desirednumlight shielded by the walls of the upper chamher so that it will notbe blown out. Thus the discharged gases will be effectively consumed,while danger of baokfiring is obviated by reason of the screens in theflue below the burner.

While I have illustrated and described with particularity only asingle'preferred form of my invention, I do not desire to be limited tothe exact structural details thus illustrated and described; but intendto cover all forms and arrangements which come within the definitions ofmy invention constituting the appended claims.

I claim 1. In a device of the character described, a vertical flue, amember closing the top of the flue and containing a large lower chamberand a small upper chamber communicating therewith, said member beingperforated at the bottom to permit gases to rise from the flue into thelower chamber, there being an outlet from the upper chamber, and meansfor maintaining a pilot light in the upper chamber.

2. In a device of the character described. a Vertical flue, a memberclosing the top of the flue and containing a large lower chamber and asmall upper chamber communicating therewith, said member beingperforated at the bottom to permit gases to rise from the flue into thelower chamber, there being an outlet from the upper chamber, and a gasconduit opening through one side of the upper chamber to provide a flameextending transversely of said upper chamber whereby the gas issuingfrom said flue is ignited.

In testimony whereof, I sign this specification.

LOUIS KESSLER.
